MPS Options

[Bullet]

I can seem to get my 914 to not run Rich. I have checked Injector spray paterns, replaced cap,rotor, points, condensor,plugs, plug wires. and belive that my vacuum routing is correct. I question the integrety of the MPS. if i remove the vacuum hose that runs to it and clamp it off i get no change at all in performance. I was told by a co-worker that i should drill out the riviots and check to see if it is gummed up. I just removed it and am getting ready to take it apart, when out of curiousity I ohm checked the teminals and this is what i got : pin 8 - pin 10 350 ohms, pin 7 - pin 15 90 ohms. is this normal? does anyone know of any way to check the MPS. Or could any one do a quick ohm check on theese terminals to let me know if that is a correct reading? any help would be greatly apreciated.

Well, I won the auction for the MPS. recived it in the mail today and installed it after work. I pulled a vacumm on it and it held 20in, i then did a resistance check and it was right as specs called for. My car is now not running ritch (IMG:style_emoticons/default/laugh.gif) . But it still has a missfire. and the vacumm guage bounces from 8in to 10in I started doing a cylinder power ballance test. by removing 1 injector at a time checking for rpm changes. all cylinders are affected except for Cylinder #3. I get no change whats so ever. So I pulled the plug wire and checked for spark (good), thrn pulled the Plug and checked for spark through the plug (good) removed injectors #3 and #4 and both are spraying in a good CONE pattern. I set the Dwell a few weeks ago, and dont think that has changed. All i have been able to do is set the timming to TDC to keep it running. I cant set it to 27 degrees at 3500 because the engine wont hold the RPM. I can get it to 3500 but it drops down to about 3000 when i hold the throttle in the same position. WTF am i doing Wrong? anyone have any ideas on what could be going Wrong? Also all my Vacumm hoses are routed acording to the Diagram on Pelicanparts.com.
